That burst of pace to go around Dan Biggar will have done his hopes of keeping his place in the line up for the final, should Exeter make it, no harm.
Don’t forget he was playing Welsh Premiership rugby just a couple of seasons ago.
Exeter 28-12 Northampton
Any hope for Northampton in this one or have Chiefs already done enough?
Alex Cuthbert is nearly away for another score for the hosts but Saints close the door in time on him.
Might just be a temporary lull though.
Tom O'Flaherty, con Joe Simmonds

A marvelous solo score for Exeter from Tom O'Flaherty comes moments after that Dave Dennis try.
The winger burst away from the halfway line up the middle and then had the speed to escape the chasing defenders. Crowd on their feet after that one.
Simmonds on target again off the tee.
Dave Dennis, con Joe Simmonds
Image source, Getty ImagesExeter back on it and they have a third try.
It's Dave Dennis who sneaks in to dot down inches out from the line after some picks-and-go's off that line-out.
How crucial might that be? Simmonds adds the extras to push them into a nine-point lead.

Interesting tactical change in this second half.
Northampton have moved their man mountain winger Taqele Naiyaravoro to the opposite wing to go up against the much smaller Tom O’Flaherty.
The big Pacific Islander had got little change out of Alex Cuthbert in the first 40, but has already had one good run in the opening minute.
Exeter 14-12 Northampton
Northampton concede a penalty for being offside 30 metres out and fairly central.
But Exeter again back themselves to kick for touch and try and score the try.

Some early energy from Northampton in the second half as they work it through their back line.
But Exeter organised in defence and force it back on to Saints.

Two points in it. Will it go to form or will we have an upset to talk abut come full-time?

Andy: Wow ... Saints should have been going into the break 19-14 up!
David: Following the rugby here in France. This looks like it could be a closer game than the first. Still fancy Sarries in the final though!
It must be noted that there is a facepalm emoji in that tweet from Andy. A pretty good way of summing up that missed chance for Saints at the end of the first half.
FT: Saracens 44-19 Gloucester
A place in the Premiership final is the prize for the winner of this remember.
Whoever it is will join Saracens at Twickenham next Saturday after the defending champions won 44-19 against Gloucester earlier.

Image source, Getty ImagesA half of two halves if ever there was one.
Exeter dominated the first 20 minutes , but what a fight back by Saints.
This one really could go either way. Thank goodness half-time is here as everyone here at Sandy Park needs to catch their breath.
HT: Exeter 14-12 Northampton
Well, well.
What a first half that was - not entirely how many pundits might have scripted it.
More of the same after the break please...
Exeter 14-12 Northampton
That's the break but it was so nearly the perfect end to the first half for Northampton!
Rory Hutchison burst through from halfway and passed inside to Cobus Reinach - who spills it!
Almost the rugby union equivalent of missing an open goal!
Had the scrum-half clung on, it would have been Saints in the lead for the first time.
Exeter 14-12 Northampton
Tom O'Flaherty back on the field to bring Exeter back to 15 men.
Meanwhile, it opens up for Northampton in attack and Dan Biggar has a drop-goal attempt in the closing seconds of the half.
But the Welshman skews that one easily wide of the sticks.

Northampton drift out of touch on the right side as they try to find a gap out wide.

What a turnaround! Fair play to Northampton, they looked dead and buried but those two tries mean it’s anybody’s game.
Rory Hutchinson’s superb handling for Tuala’s try needs to be seen to be believed.
And with Exeter down to 14 men now it's Saints in the driving seat.
Exeter 14-12 Northampton
Exeter rally and again force an error from Northampton on halfway.
Joe Simmonds kicks for touch once more to try and set it up off the line-out but Chiefs can't execute this time and Northampton can clear their lines.
Ahsee Tuala, Dan Biggar missed con
My word - here we go!
What a comeback from Northampton and what a score from one end to the next.
It's Ahsee Tuala who finishes it off eventually, but it was initially made by a great break by Tom Collins as he chased down a high kick form Dan Biggar from his own 22.
They shifted it left and then across to the right for Tuala to dot down, but Biggar is wide with the conversion so Exeter stay ahead by two points.
Penalty
It's a penalty try for Northampton and a yellow card for Exeter's Tom O'Flaherty!
Game on all of a sudden with Chiefs down to 14 men!
Exeter 14-0 Northampton
James Fish drops the ball over the line, but wait - we could still have points for Northampton here due to some off-the-ball antics by Exeter winger Tom O'Flaherty.
